6-Volt: Use a DC voltmeter of approximately
0-15 volt range. A normal reading is from 5.5
to 6.5 volts.
The above checks normally are sufficient.
Further checks may be made as follows:
connect a low range ammeter in series with
one magnet lead. Correct amperage readings
for each coil voltage and unit size are found
on page 5. These readings are taken with the
power on and the potentiometer control in
the maximum position.
Ohmmeter checks should be made with the
power off and the circuit open. (To be certain,
disconnect one lead to the magnet.)
Compare resistance to the data on page 5.
If the above checks indicate that the proper
voltage and current is being supplied to the
coil, mechanical parts should be checked to
assure that they are in good operating condi-
tion and properly installed.
Repair and Replacement
Performance Plus Unimodules will provide reli-
able and consistent performance throughout the
exceptionally long life of the friction facings.
Their long life results from the exceptional wear
resistance of the ceramic material. The low wear
rate also results in a longer burnish time to
"mate" the friction surfaces. Alignment of the
friction surfaces of both clutch and brake are
also very critical. Therefore, these units are not
field serviceable. All repair work must be done
by the Factory where alignment and burnishing
can be closely monitored.
Please note that units with damage to the non-
wearing components, such as housings and
shafts, are not repairable. The factory will evalu-
ate returns and determine if they can be
repaired.
